美国采购需求：荧光笔、凝胶荧光笔、闪光笔、白板笔、干擦笔、颜料眼线笔

I recently purchased a set of dry erase markers, but unfortunately, the package arrived opened and the product isn't in brand-new condition. I expected to receive a completely undamaged item, especially since I paid full price. I would like to request either a replacement package or a refund for the purchase. I'm willing to send the current item back for verification. Please advise on how we can resolve this issue promptly. Thank you!
